Question 1

What happens to species richness as the area increases?

  • Increases indefinitely
  • Increases to a limit
  • Decreases

💡 Hint: Consider the relationship we discussed.

Question 2

The slope of a species-area relationship for larger areas typically ranges from:

  • 0.1 to 0.2
  • 0.6 to 1.2
  • 1.5 to 2.0

💡 Hint: Think about the difference between small and large area studies.

Challenge Problems

Push your limits with challenges.

Question 1

A conservation biology team is studying two different regions: Region A has an area of 100 square kilometers and Region B has an area of 400 square kilometers. Based on the species-area relationship, predict the difference in species richness they might encounter, and explain your reasoning.

💡 Hint: Use the formula discussed in class to guide your estimate.

Question 2

If the slope Z of the species-area relationship in a temperate rainforest is measured at 0.15 and in a tropical rainforest is measured at 1.10, what does this indicate about biodiversity in these ecosystems?

💡 Hint: Consider what a steeper slope implies for biodiversity.
